I have walked and stood and moved with my legs for an estimated 10 hours a day, which means I have used my legs for 171,550 hours in my lifetime. These legs have moved me to new cities, up mountains and down streets winding through places new and old.

What if actresses could stop shaving years as regularly as they do their legs? What if the only numbers that mattered on our resumes referred to how long we stayed at one place? What if we could love without worrying about the birth dates of potential partners?

We heard from women in their 70s on our blog at 70candles.com and in 70candles discussion groups across the country, from New York to Texas. With decades of life ahead for many of us, it's a great time to reassess our lives and examine our options. Here are the topics that matter most to women in their 70s.

Because we're reluctant to talk about our own vanity-driven alterations, we tend to want to dismiss and condemn those of others. The real objection to Zellweger's new face isn't that she has one. The objection is that we can't pretend it didn't happen.

The place I'd like to hit the "pause" button is not on my menses, which I've never minded much and will miss when the egg factory closes down for good, but on our society's terror of human aging, fragility and change.

I am not menopausal, nor have I gone through menopause, so I obviously don't know what is in store for me, but if the experience of those nearest and dearest to me is any indication, it is unlikely to be a fun fest.

Sporting a rhinestone top and hot pants, her feet barely fitting into her glittering, impractical heels, Mrs. Longstreet would embark on her morning shopping trip. As this Suburban Gypsy Rose Lee strutted down the frozen food aisle for her big number, her flesh sagged like a flag at half-mast.

We condemn the pressure placed on our daughters to be and look perfect. And then, we place almost the same pressures upon ourselves to be forever young, to repel the forces of aging and to glean our sense of self from our faces rather than our lives.

Nothing seemed to be missing other than her waist, which is definitely gone. At one point we did determine that it might be hidden under her breasts, but even after lifting her breasts to their pre-breastfeeding position, her waist could not be located.

While gender differences have narrowed in so many ways, when it comes to hair loss, the gap remains wide. A clean-shaven head may be commonplace among men, but it continues to be a rare and complicated choice for everyday women. Why is that?

I have great tits. I'm not telling you that to brag, I'm just telling you that because there's not one part of my body, talent or personality you'll ever hear me say is great. But I have great tits, for a normal person, who doesn't photograph them for the Internet.

Can you please start wearing nicer bras so you don't end up almost 40 years old with a "lingerie" drawer full of Champion sports bras from Target? Please do some leg work; you are going to get busier later in life. Don't make Old Christie do everything.

We wished for a road map, but knew of none for the years ahead in this new era of extended longevity. What were women in their eighth decade doing with their time? What were their hopes, dreams, expectations? What does "old" look like these days? We decided to find out.

Whether you are a teen or over 60, your body undergoes constant physical change. And as these changes occur, they evoke a set of emotional responses that relate not only to your age, but to the circumstances associated with your stage of life.

I don't wish to be younger (maybe because I'm blessed with good health and plenty of energy), but I can't deny that I'm slower. We don't spend enough time sharing with each other about our blessings or, more to the point, about our fears about aging.
